Hello Ramon,

with a co-author hat on, but without loading the draft completely into
brain again, yes, this was the intent. The reasoning behind is to
provide an initial baseline for the state present on the PCC, agreed by
both PCE and PCC.

This simplifies the protocol design a bit, as we do not have to deal
with state synchronization being half-done.

Furthermore it gives the PCE a chance to attempt to re-negotiate the
session parameters based on the problem it has seen with the PCRpt.

Regards,
Robert
